Get started for freeWhen you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twice as much work when throwing the ball, does it go twice as fast? Explain.
If we know that a force of \(5 \mathrm{~N}\) acts on an object while it moves 2 meters, can we calculate how much work was done with no other information? Explain.
What is a conservation law? What is the basic approach taken when using a conservation law?
Two cranes are lifting identical steel beams at the same time. One crane is putting out twice as much power as the other. Assuming friction is negligible, what can you conclude is happening to explain this difference?
Could the linear momentum of a turtle be greater than the linear momentum of a horse? Explain why or why not.
